THE RESET BUTTON ENGLISH USE’S MANUAL MULTI-CHANNEL CABLE FREE REMOTE THERMO SENSOR MODEL: THC268 INTRODUCTION Congratulations on your purchasing the THC-268 Remote Thermo Sensor. The Remote Thermo Sensor is used with the Oregon Scientific 433MHz Multi-Channel In-Out Thermometers , Wireless Weather Stations, Weather Clocks etc. to monitor temperature changes of remote or outdoor sites. Operation is easy and no wire installation is required. See the user’s manual of your main unit for further information. This button is only used when the unit is operation in an unfavorable way or malfunctioning. Use a blunt stylus to hold down the button. All settings will return to their default values. HOW TO USE THE TABLE STAND OR WALL MOUNTING CAUTION - The content of this manual is subject to change without further notice. - Due to printing limitation, the displays shown in this manual may differ from the actual display. - The contents of this manual may not be reproduced without the permission of the manufacturer. This sensor comes with a wall-mount holder and a removable stand. Use either to set up the unit. MAIN FEATURES: 1 A LCD Displays the current temperature monitored by the remote unit and indicates the selected channel PRECAUTIONS B LED INDICATOR Flashes when the remote unit transmits a reading 1. Do not immerse the unit in water. C TEMPERATURE SENSOR PROBE On 10 feet ( 3 meters ) cable. D °C/°F SLIDE SWITCH Selects between Centigrade ( °C ) and Fahrenheit ( °F ) 2. Do not clean the unit with abrasive or corrosive materials. They may scratch the plastic parts and corrode the electronic circuit. 3. Do not subject the unit to excessive force, shock, dust, temperature or humidity, which may result in malfunction, shorter electronic life span, damaged battery and distorted parts. E CHANNEL SLIDE SWITCH Designates the remote unit Channel 1, Channel 2 or Channel 3 4. Do not tamper with the unit’s internal components. Doing so will invalidate the warranty on the unit and may cause unnecessary damage. The unit contains no user-serviceable parts. F RESET BUTTON Returns all settings to default values 5. Only use fresh batteries as specified in the user’s manual. Do not mix new and old batteries as the old ones may leak. G BATTERY COMPARTMENT Accommodates two AA-size batteries 6. Always read the user’s manual thoroughly before operating the unit.

Insert batteries for remote units before doing so for the main unit. ( Main unit of models listed under optional items ) This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) This device must accept any interference received, including interference that may cause undesired operations. 3. Place the main unit as close as possible next to the remote unit, reset the main unit after installing batteries. This will ensure easier synchronization between the transmission and reception of signals. Warning: Changes or modifications to this unit not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. 1. Assign different channels to different remote units. I WARRANTY This product is engineered to give you years of satisfactory service if you handle it carefully. Here are a few precautions: 4. Position the remote unit and main unit within effective transmission range, which, in usual circumstances, is 20 to 30 meters(upto 100 feet). Note that the effective range is vastly affected by the building materials and where the main and remote units are positioned. Try various setups for best result. Though the sensor is weather proof and meant to be used outdoors, it should be placed away from direct sunlight, rain or snow. BATTERY AND CHANNEL INSTALLATION The remote unit uses two AA-size batteries. To install them, 1. Remove the screws on the battery compartment. 2. Select the channel number on the CHANNEL slide switch. 3. Select the temperature display unit on the °C/°F slide switch. 4. Insert the batteries strictly according to the polarities shown inside. 5. Replace the battery compartment door and secure its screws. CHANGE CHANNEL Once a channel is assigned to a unit, you can only change it by removing the batteries and repeating the above procedure. FCC : NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: orient or relocate the receiving antenna. - Increase the separation between the equipment and receiver. - Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. - Consult the dealer of an experienced radio/TV technician for help. LOW-BATTERY WARNING Replace the batteries of the sensor when the low-battery indicator of the channel represented by the sensor shows up on the main unit. Company Name: Oregon Scientific, Inc. Address: 19861 SW 95th Place, Tualatin, Oregon 97062, USA Telephone Number: 1-800-853-8883 OPERATION Once batteries are in place, the sensor will start transmitting samplings at 40-second intervals. The current temperature will be shown on the LCD in the selected unit ( °C/°F ) at the designated channel. The unit ( °C/°F ) shown on the main unit is determined by the setting on the main unit. 11 HOW TO INSTALL THE TEMPERATURE SENSING CABLEG Secure the sensor to an area you want to monitor. Do not expose it to direct sunlight.
